Windows problem after deploying GPO

Hi
I’ve run in to a problem after deploying a GPO. The GPO contains user-configs on internet explorer.

When i log on as the user connected to the GPO Windows asks if I should run or deny several files that should start automatic, files like rundll32, my anti-virus program and other windows components.

I get the same effect in win XP as win vista. The user hasn’t admin rights.

If i disable the GPO then I don’t get these questions.

Thanks
